G which conducts the `l The part' H l mantlesupport K to be' i tightly together.` is adapted to receive is in accordance with the natural tendency; hence a proper suppl 'i .cured -in'4 the burnertube. In order to effect abetter and air and toincrea mixing of theses, se the speed of the l'ow-l mouth or opning'-D. of the tube C'is narrower than is thello'wer part shown in 'the' drawing result of the upward low of the ming and airand ofthe narrowingof the tube at' the part l) ofthe tube C ed gas-burner and of proper shape or form at the mouth L of the Bunsen-burner and the mantle is 1endered completely ing of the mantle is avoided. In a double, invertedgasburner or a gas-burner having a plurality of inverted mouths, as shown in Fig. 2, the narrowing of the tube C as at D is usually essential to securing an eflicient, proper iiame. In a single. inverted gasburner, as shown in Fig. 1., the narrowing of the tube C as at I) greatly improves the fiame andthe incandescent efl'ect of the mantle. In practice, if the diameter of the tube C is 1/2 an inch the diameter of the exit D should be about 3/8 of an inch, the principle, however, being that. in any given case the tube into which the mingling gas and air enters should be made sufficiently narrower at an upper part-to insure a proper mixing of the gas and air and a sufficientspeed of flow.

T he pipe EFG is greater in diameter than from which the minghng gas and air flow into it. The greater .diameter or extent of. opening of the pipe EFG permits'the gas and air issuing from the same effect is secured y the greater diameter or extent of opening of the part H over the diameter or extent. of opening ofthe pipe EFG, or of the art F, as shown in Figs. i and 2. In a doub e, invertor inverted gas-burner having a plurality of inverted mouths, the part E of the pipe EF G should be greater in diameter than the parts F to insure a proper supply of gas and air Fto the several parts F, as shown in Fig. 9

wise it would and the In an inverted gas-burner, constructed ac-` cording to this invention, the gas and air are pernntte'd to flow into the burner-tube and to mix below and to one side of the bunsen- The overace where ,the holes this invention. overheating'tends to the flame to ilash back and burn within the burner-tube at the holes for the admission of air. Moreover., in an inverted burner made according to this invention the u ward iiow of the mingling 'gas and air, the rapidity of their iiow and the length and curve of pipe through which they flow also serve to prevent the flashing back of the flame.

In the dra\ vings the tube C diminishing incandescent and blackene admission of air to the burner-tube. and the burner-tube arev above the bunsen- .name 1s avoided by seance l tion of these parts in separatepieces is unnecessary to secure the results above del scribed. and the tube C with the narrowing pipe EFG v. ull

y than the diameter or extent of opening of the part D, may be constructed in one piece or in any other convenient manner, provided only that the principles above described be observed. I

'hether the tube C with the narrowing at its upper end Dis made separate and distinct from the pipe EFG or whether the tube C with the narrowing atits upper end and the pipe EFG are constructed in one piece or in any other convenientmanner as above explained, the tube C and that' part of the pipe EFG which ascends constitute an ascendin or upward duct.

D The narrowing of the upward duct at some such point as D should be at an upper part of the upward duct, composed of the parts described, that is to say, the narrowing of the upward duct at some such point as D should be at a point or' place at some distance above the lower end of the upward duct, as shown in. the drawings.

An advantage in the `construction oi' an inverted gas-burner in accordance with this invention, is that one or more efficient bun-- sen-dames can be obtained from arms F F supplied with mixed gas and air from a single urner tube E with holes or openings BB, for the admission of air, as shown in Fig. 2.

What- I claim is;

1. In a gas-burner for use with mantles for incandescent gas-light, the combination of an ascending duct for gas and air which diminishes in extent of opening at a point above the lower end of the ascending duct, and a descending duct provided with a downwardly opening orifice for the exit and ignition of the gas and air mixture and the formation upon ignition, of an inverted ame, substantially as described.

2. In a gas-burner for use with mantles for incandescent gas-iight, the combination of an upward duct 'for gas and air which is provided with an inlet for air ata lower part an@ which appreciably diminishes opening at an upward point of its ascent, and a downward duct provided with a downwardly o ening orifice for the exit and ignition of t. e gas and air mixture mation, upon ignition, of an substantially as described.

3. In a gas-burner for use with mantles for inverted flame,
